Run Spatial Growth-Transform network simulation

This function uses a Spatial Growth-Transform (SGT) model to run a spike simulation on a given network object for a specified matrix of membrane currents over time. A matrix containing the spike traces of all neurons over time after the simulation (neurons as rows, sample times as columns) is saved in the network object, along with a vector of spike counts for each neuron in the network. Both are returned on the R side in a list.

Usage

run.SGT(network, I_stim, dt = 0.001, v_initial = -70)

Arguments

network

Network object on which to run the simulation.

I_stim

Matrix of stimulus currents, with rows representing neurons and columns representing sample times.

dt

Time step length in ms (default: 1e-3, i.e., 1 micosecond time steps).

v_initial

Initial value for membrane potential, applied to all cells (default: -70 mV).

Value

List containing the following elements:

v_traces

Matrix of simulated sub-threshold voltage + spike traces for all neurons over time (neurons as rows, sample times as columns).

spike_counts

Vector of spike counts for each neuron in the network.
